How do I use SlimStampen?

Getting started with SlimStampen is very easy:

Register on our app by going to .

Follow the steps on the screen to create an account

Create a lesson, or open someone else's lesson in the library, and start learning! 

While learning you will always see a question, such as a word or picture. You can then choose or type in an answer. SlimStampen works a bit like a traditional quiz in that respect, but with a few key improvements that make learning more efficient and effective!

How does it work?

When you start a lesson, you will first see a question with an answer. Subsequently, you can answer yourself. After answering you will get feedback as to whether you got it right and what the correct answer was.

During every answer you give SlimStampen looks at which questions are already correct, where you still seem to have doubts, and which questions you have not yet fully mastered. SlimStampen then estimates which question you can best practice by looking at which question you are almost going to forget. Next, you will see the question that helps you learn best and most quickly!

Collect all the lesson's crowns and track your progress

You can always see how well you already know the material and how much progress you have made, because the app keeps track of what you have learned and what you have mastered. 

Practice what you find difficult

In addition, there is also an opportunity to practice the twenty questions from the lesson group that are the most difficult for you at that moment. After practicing these you won't encounter as many difficulties the next time you practice a specific lesson with those questions. 


SlimStampen is a digital tool for learning words and concepts. It uses an adaptive learning algorithm developed at the University of Groningen (RUG)

Students choose a lesson and are then shown one of the facts from that lesson. The first time they are offered the answer, after that it is up to them to choose the correct answer, type or speak. After each item, the student receives feedback. 

Learn more efficiently with the algorithm

The algorithm adapts to the student and each time presents the item that will help the student learn most efficiently. Based on data collected at each practice moment of a fact, the algorithm can calculate how long it will take for a certain fact to be forgotten. On the basis of this, it decides to present a fact again just before it is forgotten. By prioritizing facts that are almost forgotten and keeping track of the individual's learning process, the algorithm can determine when new facts should be introduced. 

Teacher screen

In the teacher screen you can see for each student to what extent they have mastered the material of different lessons or weeks. This way, SlimStampen provides personalised approach. An overview for all students is maintained for you as a teacher.

Creating a lesson

There are several options for the lessons you put together. You can put both the questions and answers in text, but images and audio files are also possible for both the question and the answer. You can also opt for multiple choice questions, or questions where the student has to type in the answer himself. If you want to see more options, see the 'How it works' page.
